I saw footage of some high rises where it looked like just about everything but the steel frame itself was wiped out - the blast wave came in one side and went out the other, taking everything else with it.
And as for the "fireworks" fire before the big bank . . . I just have to wonder whether or not it was some of Hezbolla's munitions rather than simple celebratory fireworks.
I could be wrong but most videos of munitions going off that I've seen they weren't that flashy(?). I'm sure a lot would depend on what kind of munitions.
I've not seen anything
YET that would made me think this was anything but a Murphy + Murphy = Boom
